4 Claims.

This invention relates to hot water heaters or boilers for use either inheating water for domestic purposes or for heating water that is to beconveyed to radiators o-r the like for heating purposes.

An object of the present invention is to provide a hot water heater,boiler or furnace having therein a plurality of heating surfaces againstwhich the water inthe boiler contacts to the end that the water as itenters the boiler is almostinstantaneously heated. y

A further object of the invention is to provide in a hot water furnace,heater or boiler a multiple heating surface involving such anarrangement of angularly related heating surfaces whereby maximumsurface within a minimum amount of space is obtainable.

The invention, together with -its objects and advantages, will bebe'stunderstood from a study of the following description taken inconnection with the accompanying drawings, wherein:

Figure 1 is a perspective view of a hot water heater, boiler or furnaceinvolving the features of the present invention, with certain partsbroken away and shown in section.

Figure 2 is an end elevational view of the Yheater with certain partsbroken away and shown in section; and

Figure 3 is a vertical sectional View taken substantially on the line3-3 of Figure 2.

Referring to the drawings by reference numerals it will be seen that inaccordance.v with the present invention there is provided a boiler orcasing shell 5 of suitable shape. Arranged in the bottom of the chamber5 and spaced from the bottom wall of the casing 5 are partitions Iidisposed adjacent opposite sides of the casing 5 and dividing the latterinto a lower heating chamber 1 and an upper water chamber 8.

For the chamber 8 the casing 5 is provided at either or both endsthereof with doors 9 thru which access may be had to the chamber 'I.Inthe present instance there is shown arranged within the chamber I twogas burners Ill, although it will be understood that in lieu of gasburners, electric heating devices, coal, wood, or other fuel may beemployed.

Formed integral or otherwise associated with the partitions 6 arevertical substantially Wedgeshaped, hollow formations or fins IIarranged in a row extending from one end wall to the other inner Walllof the casing 5. These formations II are open, as clearly shown inFigure 3, along their bottom edges and vertical end edges and at theirupper inner corners are formed integral with or have otherwiseyassociated therewith the lower edge portion of a spaced opposed Zig-Zagplate I2. Atv their upper edges the plates I2 are connected byhorizontal plates I3 from which rise hollow, substantially wedge-shapedforma-- tions I4 that are arranged at substantially right angles to theformations I I and are open at their bottom edges.

The formations I4 at one upper corner are integral with or otherwiseassociated with a common smoke conduit I5 that has extending through theadjacent end wall of the shell or casing 5 an outlet I6 adapted to beconnected with achimney flue or other outlet for the products ofcombustion.

Extending from the top` of the shell or casing 5 are outlets I'I towhich are connected conduit pipes (not shown) through which steam orwater is conveyed to the point of use.`

Access to the space between the plates I2 may be had through an openingI8 provided in one end wall of the casing 5, and for the opening I8there is provided a removable door or closure I9 (see Figures l and 3).

Also, tapped into the casing 5 at opposite sides thereof and above thepartitions 6 are cold water inlet pipes 2U.

Also tapped into opposite .side walls of the casing 5 above thepartitions 6 are blow-off valves 2l.

From the above it will be apparent that the smoke or products ofcombustion pass upwardly into the hollows of the formations II andbetween the rows of formations II to the space between the zig-zagplates I2, passing from this space intothe hollows of the formations I4to exit through the conduit I5 to the smoke flue or chimney with theresult that the formations II, plates I2, and formations I4 serve as hotplates or heat radiating surfaces that quickly raise the temperature ofthe Water admitted into the chamber 8 from the inlet pipes` 20. Thus, itwill be seen that the water will be quickly converted into steam and thesteam carried 01T to radiators or the like through the outlets I'I andconduits (not shown) connecting the outlets I'I with such radiators.

In connection with the above, however, it will also be understood that awater circulating system including my improved heater may be resorted toto the end that the water heated in the chamber 8 may be carried off fordomestic use.

It is thought that a clear understanding of the construction, utility,and advantages of a water heater or furnace involving a multiple heatingsurface arrangement as herein illustrated and described will be hadwithout amore detailed description.

It is also to be understood that while I have herein shown and describeda preferred embodiment of the invention, that it is in no wise intendedto restrict theinvention to the precise form herein illustrated anddescribed other than may be necessary to meet the requirements of theprior art or the scope of the claims hereunto appended.

Having thus described the invention, claimed as new is: n

1. In a liquid heater of the character described, a casing, a pair ofpartitions extending inwardly from opposite side walls of the casing inspaced relation to the bottom of the casing and dividing the latter intoa lower re compartment and an upper water compartment, a heating mediumdisposed in the re compartment of the casing, a multiple heating surfaceassembly connected with andextending upwardly from said partitions andforming a flue for the passage of the products of combustion, saidassembly consisting of a` row of spaced hollow formations rising fromeach partition and extending back from the inner edge of the latter,vertical zig-Zag plates extending upwardly from the inner upper cornersof said rows of formations, and a series of hollow vertical formationsextending upwardlyfrom the upper portions of said Zig-zag plates anddisposed at substantially right angles to the first-mentionedformations.

2. In a liquid heater of the character described, a casing, a pair ofpartitions extending inwardly what. is

from opposite side walls of the casing in spacedV relation to thebottom. of the casing and dividing the latter into a lower firecompartment and an upper water compartment, a heating medium disposed inthe fire compartment of the casing, a multiple heating surface assemblyconnected with and extending upwardly from said partitions and forming aue for the passage of the products of combustion, said assemblyconsisting of a row of spaced hollow formations rising from eachpartition and extending back from the inner edge of the latter, verticalZig-zag plates extending upwardly from the inner upper corners of saidrows of formations, a series of hollow vertical formations extendingupwardly from the upper portions of said Zig-zag plates and disposed atsubdisposed in Vthe fire compartment of the casing,

a`- multiple heating surface assembly connected with and extendingupwardly from said partitions and forming a flue for the passage of theproducts of combustion, said assembly consisting of a row of spacedhollow formations rising from each partition and extending back from theinner edge of the latter, vertical zig-zag plates extending upwardlyfrom the inner upper corners of said rows of formations, a series ofhollow vertical Yformations extending upwardly from the upper portionsof said Zig-Zag plates and disposed at substantially right angles to thefirst-mentioned formations, a smoke conduit connected with and common tothe last-mentioned series of formations, said last-mentioned series offormations opening at their bases into the space between said zig-zagplates, cold water inlet pipes extending into the casing from oppositesides of the latter and above said partitions, and blow-off valves forthe water compartment mounted at opposite sides of said casing abovesaid partitions.

4. In a heater of the class described, a liquid container having a fluetherein for the passage of heat, the lower walls of the fluebeingcomposed of rows of 4horizontally spaced hollow formations, the lowerends and inner side edges of the formations being open to the heatandthe spaces. between the formations forming portions of the liquidchamben' vertically arranged Zig-zag plates connected with the innerupper corners of the formations and Vforming the intermediate part ofthe flue, a row of horizontally spaced formations having their lowerends in communication with the space between the zig-zag plates andforming the upper portion of the flue and outlet means connected to theupper portion of the lastmentioned row of formations.
